ADS1299 Drivers for Portenta H7

I am working with the ADS1299 Dev Board from TI , and facing a lot of problems to connect it with arduino protenta h7 , I did something similar before with the Pico and it was working but I am unable to integrate it with Portenta H7. Dropping my libs repo below , any help would really be appreciated : My Library for Portenta H7 with ADS1299

Also sharing the Pico Library for ADS1299 which I am using as refference: Pico Lib for ADS1299 And the Driver for Pico itself was made using this lib: Arduino ADS1299 Driver

Greetings !
These problems occur due to the Memory Storage of the Boards. Try checking the memory Assignments and Usage of the memory on your Board.
Some Boards need avr commands and Libraries for memory Configurations and Alterations.

TRY:
1)Checking the SPI connections are Perfect.
2)Commands used for fetching the data.
3)Basic: If it is able to read all the register values
